B.10. Lists and ArraysPerl has a number of features that make it easy to manipulate an entire list or array. B.10.1. map and grepIn Chapter 16, we mentioned the map and grep list-processing operators. They can do more than we could include here. See the perlfunc manpage for more information and examples, and check out the Alpaca for more ways to use map and grep. B.10.2. The splice OperatorWith the splice operator, you can add items to the middle of an array or remove them, letting the array grow or shrink as needed. (Roughly, this is like what substr lets you do with strings.) This effectively eliminates the need for linked lists in Perl. See the perlfunc manpage. |
